Doesn't surprise me, too bad though. I'm not in need of one since I use
electric water pump, but I was curious if they were working well. If I
was using a mechanical pump, I'd definitely pursue it for my "off road
vehicle"

One source was Racetech. They do a Chevy, Ford, and Mopar water pump with a alternator built into the pulley. So-Cal based. They weren't opposed to aircraft, but needed a fairly large pulley to put the alternator in. The rib belt Mazda pulley was way to small diameter. I talked to him about a e-shaft pulley alternator, but it would have required a totally new design and was beyond my means.
